HSPiP exists to give users practical access to the power of HSP. The 3 Edition continues the tradition, adding in-depth resources for the enquiring user. Here’s what’s new:

1. The Interface
Improved form layout, Help and eBook reader
Search is now more powerful and intuitive
Expanded HELP section for all functions

2. The core Sphere program
Improved fitting process that gives tighter “Sphere” fits with difficult datasets.
More fitting choices including “gradient” fit for data scored 1-6, “MVol corrected” fit to take into account the molar volume of the solvents, and “Force to δTot”
A visual guide to Environmental Stress Cracking tendency

3. The core Datasets
A massive dataset of 10,000 compounds with HSP plus key data on density, Melting point, Boiling Point, Critical Parameters, Antoine Constants and much more.
Dataset search for HSP analogs by Distance (+ Boiling Point) or functional groups
Practical datasets on GRAS, Food/Cosmetics, Sigma Aldrich Flavors and Fragrances, Deuterated NMR solvents, Skin Permeation Enhancers and much more.

4. The eBook
Greatly expanded with new sections on Ionic Liquids, Glove safety, Polymer adhesion/viscosity/solubility – putting it all together with HSP.
A new chapter on “How to measure your first HSP”

5. Data prediction
The powerful Y-MB method to estimate HSP is now more powerful and more reliable, especially for larger molecules
Surfactant HSP prediction via Y-MB
Polymer Smiles has been revised and updated with a large database and is also more reliable in its estimates of AB, AABB co-polymers
New HSE “read-across” ability – compare two chemicals for their key properties including HSP distance
New Azeotrope and Vapour Liquid Equilibrium predictor
New Solubility predictor

6. Polymers
A guide to the polymers in the database and a data reliability score to help you choose the values to use.
New modeller of polymer solution theory
New modeller on polymer adhesion and viscosity based on the polymer physics of HSP – as described in the greatly expanded Adhesion chapter

7. Solvent Optimizer
New “1” and “3” solvent optimization options in addition to the available “2” option
New “absolute time” evaporation modeller, with improved algorithms
New “Wet bulb” and “Blushing” estimator for evaporation – water condensati on during film formation or not.

8. Diffusion modeller
Increased power and precision
Proven capability to describe diffusion “cases” and “anomalous supercases”
Allows estimation of surface mass transfer coefficients
Calculates lag-times in permeation experiments also with a significant surface condition
Now suitable for modelling skin permeation with lag times
Allows estimation of concentration dependent diffusion coefficients from permeation data

9. Tools
GCRI (Gas Chromatography Retention Index) predictor
Evaporation modeller (absolute rates in air flows)
Deuterated NMR solvent mixtures choice (via Solvent Optimizer)
